Unmatched Thermal & Electrical Performance

Higher Heat Capacity

  • 2,103 J/kg·K @ 60°C

  • 15–20% higher than GTL fluids such as Shell S3X

  • Reduces chip temperatures for improved stability and prolonged hardware lifespan

​

High Thermal Conductivity

  • 0.145 W/m·K @ 40°C

  • Rapid heat movement from chip → fluid → heat exchanger

  • Optimal for overclocking environments and sustained heavy workloads

​

Optimized Low Viscosity

  • 8.7 cSt @ 40°C

  • Lower pumping power, faster circulation, and improved system efficiency

  • Noticeable performance improvement vs. GTL-based fluids

​

Ultra-High Volume Resistivity

  • 920 GΩ·m @ 60°C

  • Outstanding electrical insulation for dense ASIC layouts

  • Maintains dielectric integrity under high-frequency workloads

​

Exceptional Plastics & Cable Compatibility

  • Formulated to prevent swelling, embrittlement, and cable jacket degradation

  • Ideal for long-term data center or mining deployments

  • Significant advantage over GTL fluids which commonly soften plastics over time
